Safety Instructions
Before using your Foredom power tool, please
read safety instructions. They are for your protec-
tion and should always be followed to reduce the
risk of personal injury or damage to the tool.
•Always wear proper eye and face protection.
Wear safety glasses or face shields whenever you
operate a Foredom or any power tool to prevent
serious eye or face injuries.
•Secure the work piece or item that you are
working on in a vise or other work holding device.
Holding it with your hand can result in serious
hand injury.
•Always use a proper dust collection system or
wear a respirator to prevent the inhalation of
dust particles, polishing compounds, or other
debris into the lungs.
•Do not wear loose fitting clothing or jewelry.
Loose clothing or jewelry can become entangled
in the rotating accessory. Do not wear items such
as neckties, necklaces, or bracelets when operat-
ing power tools. Be sure to tie back or secure
long hair.
•Secure the power tool to motor hanger or
work surface. Flexible shaft power tools can
“jump” at start up or vibrate during opera-
tion. The tool should be properly secured in
order to prevent it from vibrating off of the
motor hanger, work bench or wall.
•Never use any accessory at speeds above
its maximum rated speed. When properly
used, all of Foredom’s accessories can be
operated at the speed ratings listed in the
Foredom Accessory Catalog or specified
on kits and packaging. Always find out the
manufacturer’s speed rating before using ac-
cessories other than those from Foredom.
•For added safety and comfort while using
this power tool for carving or other applica-
tions, it is recommended that you wear a heavy
canvas or leather apron. It will protect you
from dust, debris and chips as well as help
prevent injury if the handpiece slips off the
workpiece. It will also help prevent loose
clothing from getting caught in a rotating
cutter, bur or other accessory.

• Never wear open shoes or sandals. Use
footwear that is tough enough to protect
your feet from falling tools.
•Never use or continue to use any accessory
which appears to be damaged, loose,
vibrating, or out of balance. Inspect each
accessory for cracks or flaws before using
it. Avoid knots, imperfections in wood
or metal objects like nails, which could dam-
age or catch the accessory.
•Always insert the shank or arbor of an
accessory or mandrel into the collet or
chuck of the handpiece as far as possible in
order to provide proper support and tighten
the collet or chuck securely.
•Never use excessive side pressure which
may bend or break the shank or arbor of an
accessory. Let the speed of the accessory
do the work.
•Do not stall the motor by jamming or using
excessive pressure on the accessory. This
can result in damage to the motor or
flexible shaft.
•Never operate the motor with the outer
sheath removed from the flexible shaft.
•Always disconnect the power cord before
servicing the motor or removing the flexible
shaft or sheath.
•Never operate your power tool during a
perceptible power decrease. Turn power tool
off and do not use until power is fully restored.
•Use proper grounding procedures. This tool
should be grounded while in use to protect the
operator from electric shock. The tool is
equipped with an approved 3-conductor cord
and a 3-prong grounding type plug to fit the
proper grounding receptacle. The green (or
green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or
green and yellow) wire to a live terminal. If
your unit is for use on less than 150 volts, it
has a plug that looks like sketch A below. An
adapter (sketches B and C) can be used for
connecting plugs as shown in sketch A to
2-prong receptacles. The green colored rigid
ear, lug, etc., extending from the adapter must
be connected to a permanent ground such as
a properly grounded outlet box. Some juris-
dictions, including Canada, prohibit the use
of 3 to 2 prong adapters. Where prohibited,
they should not be used. Use only 3-wire
extension cords that have 3-prong grounding
type plugs and 3-pole type plugs and 3-pole
receptacles that accept the tool’s plug. Always
disconnect the power cord before servicing
the tool. Never use in an area where
flammable vapors are present.
Never change motor direction while the motor is running.
Changing direction while motor is running can damage the motor or
flexible shaft or lead to premature wear. To turn motor off, remove foot from
foot pedal speed control, or turn dial speed control to “off” position, and set
rocker switch to “off” (center) position on motor.

OFF – no rotation.
FORWARD – counterclockwise shaft rotation.
Forward is going to be the most commonly
used setting. Right-handed people will get
the most control in the forward direction.
At Foredom we define motor rotation this way:
Forward motor rotation means that the motor
is turning an accessory (bur, bit, drill, cutter,
etc.) counterclockwise when holding the
handpiece upright in your hand and you are
looking down on to the front of the accessory.
When the handpiece/accessory is applied to
the workpiece, your viewpoint changes to the
back end of the handpiece and accessory and
the forward rotation direction can be
described as clockwise.
Forward Motor Rotation
• ONLY use Chisel or Hammer handpieces or
Angle Grinder attachment for H.30
®
hand-
piece in Forward Rotation. Using Chisel or
Hammer handpieces or Angle Grinder
attachment in reverse can damage the hand-
piece, attachment, flexible shaft, or motor
and may cause injury.
• Use the forward motor direction ONLY for
fluted burs, drills and cutters. Most will cut
efficiently only when turning in this direction.
• Many mandrels have right-hand threaded
arbor screws which will unscrew in the
reverse direction.
• Dust and debris flies away from the user
when operated in forward in the left hand.

M.SRM Bench Style
with built-in control
A complete Series SR flexible shaft power tool consists of a motor, flexible shaft and
sheath, speed control (foot or manual) and a handpiece. If you purchased a motor and control, a
handpiece will also be needed to operate the machine. Locate and identify all components, parts
and accessories you purchased before discarding the packing list and packing materials that
came with your power tool.
Please follow these directions to assemble
and adjust the shaft and sheath.
To check the shaft and sheath you
must first remove the handpiece
which is easy to do.
To remove:
1. First make sure your power
tool is unplugged. Simply pull the
handpiece off the shaft and sheath with
a firm grip.
2. With the handpiece removed, place the entire
unit on a flat surface with the shaft and sheath
extended straight. Loosen the set screw on the
motor connector. Adjust the exposed tip (hand-
piece end) of the flexible shaft so that it
extends 3/4″ (19mm) beyond the sheath. This
is done by moving the sheath in or out of the
motor connector (motor end). Shown below.
3. When the correct adjustment is made,
re-tighten the set screw in the motor connector
and re-attach handpiece onto the shafting.
Assembly Instructions
Always make sure your power tool is
unplugged during assembly!
After identifying all the components of your
power tool, assemble it in the following manner:
Assembly and Adjustment of Flexible
Inner Shaft, Outer Sheath, & Handpiece
Proper assembly and adjustment of the key tip
flexible shaft and sheath are critical for the
correct operation of your Foredom power tool.
The exposed tip
(handpiece end
of the flexible
shaft with hand-
piece removed)
must extend 3/4″
(19mm) beyond
the sheath.
Important Note: The shaft and sheath should
be checked and adjusted (if necessary) even
if you received them assembled and
attached to the motor!
To Re-attach Handpiece: while holding the black
colored metal outer sheath tip facing upward, turn
on the motor so that it is running at about half
speed and then turn it off. While the inner key tip is
still rotating, grip the handpiece and push it onto the
sheath tip with one firm motion until it snaps into
place (shown at right). This procedure will align the
key tip into the keyway slot (as shown at left). To
verify this, insert and tighten an accessory into
collet or chuck, turn on motor to low speed and
observe that the accessory rotates smoothly.

Be sure to follow the grounding
instructions on page 3 of this
manual while attaching the
speed control to a power outlet.
Please note that the power cord
on a foot or dial speed control,
and NOT the motor power cord,
plugs into an electrical outlet.
Motors should not be plugged
directly into an outlet.
Connecting the Foot Speed Control
The electrical specifications for your power tool
are listed on the label on back of motor.
It shows proper voltage and currents to use with
your power tool.
A 115 Volt, 50/60 cycle (Hz) motor can be used
with the models C.FCT-1 and C.SCT-1 foot
controls on 115 Volt AC current only. The 230
Volt, 50/60 cycle (Hz) motor can be used with the
models C.FCH-2 and C.SCH-2 foot controls on
230 Volt AC current only.
To connect the foot control to the motor, insert
the 3-prong plug on the end of the motor power
cord into the socket connector on the shorter
power cord on the foot control. With the motor
fwd/off/rev switch in the “off” position, plug the
3-prong plug on the longer power cord from the
foot control into a proper 3-prong power outlet.
When your foot is NOT pressing the foot
control, the motor should not be running.
Your foot must maintain steady contact with the
pedal during operation. Holding the handpiece in
your hand, put the motor fwd/off/rev switch in the
desired “on” position, begin with a light touch,
start out slowly and gradually increase the speed.
Finding the right speed for any specific
task is a matter of experimentation
and experience.
Hold the handpiece securely
before selecting the rotation
direction and turning the motor to
the desired “on” position.
Hanging Motor Installation
M.SR Motors should be hung up
about 30″– 40″ above the work
surface and to the right of the work if
you are right handed or to the left of
the work if you are left handed.
Use a safety clip or hook like the one
shown to prevent the motor from
jumping or twisting off an open hook
at start up or during use. Properly securing the
motor will help to prevent injury to the user.
All Foredom motor hangers come with a safety
clip (see page 15). If an “open hook” is used be
sure to secure the motor to it with wire or
heavy tape.

Operation and
General Guidelines
Always wear proper eye and face protection
when operating a Foredom
®
power tool.
Read all the safety instructions in this man-
ual before operating your Foredom Power
Tool. Proper eye and face protection must be
worn to protect you from injuries caused by
flying debris, chips, or sparks which might
result from the work being done.
It is possible to use rotary or chisel
handpieces not made by Foredom with your
Foredom flexible shaft power tool. However,
this is not recommended since their function
and safety cannot be assured by Foredom.
Your Foredom motor may be operated in a
vertical or horizontal position, but it should
not be enclosed or confined so as to restrict
air circulation. If the motor is hung up above
a workbench, be sure it is fastened securely
to the wall or motor hanger. The motor may
develop a high operating temperature (up to
100
o
F + ambient) after prolonged use, and it
will be too hot to hold. This will not harm the
motor which is designed to operate at this
temperature for prolonged periods.
Do not force the tool
Let the speed of the tool do the work. Avoid
using too much pressure. Generally, slower
speeds are used for rougher, heavier work
or when greater control over the accessory
is required for precise, delicate work. Higher
speeds are used for buffing, cutting and pol-
ishing. Read Accessory Recommendations on
pages 11 and 12 of this manual.
Voltage Decreases
Never operate a power tool during a percep-
tible power decrease. Turn off tool and unplug
until full power is restored.
Wait for motor to stop rotating before
switching between forward or reverse.
To turn motor off, remove foot from foot pedal
speed control, or turn dial speed control to
“off” position, and set rocker switch to “off”
(center) position on motor.
Do not bend shaft and sheath
at tight angle!
When operating your Foredom tool be careful
not to bend the flexible shaft too much at either
the handpiece or motor shaft connections.
Shafts and sheaths last longer when they are
used without sharp bends. If used at angles or
loops, wear will occur at the points of greatest
friction. Excessive heat and wear will occur if the
bend is too great.
Torsional Breaking Point:
Key Tip (Standard) Shaft 24in.–lb
Square Drive (Heavy Duty) Shaft 50in.–lb
Slip Joint (European) Shaft 24in.–lb
Follow these guidelines for trouble-free use:
a 4″ or larger radius, as shown, should be
maintained for shafts on all motors. There is no
way to avoid ultimate wear and under normal
conditions a flexible shaft machine may require
several replacement shafts and sheaths during
its lifetime. (Follow shaft and sheath assembly
instruction in the Assembly section of
this manual.)

30
®
, (30H), 35, 43T, 44T, (44HT) and 52:
These handpieces have been permanently lubri-
cated. Their greased-shielded ball bearings should
absolutely not be lubricated. (Handpieces listed
in brackets are for use with Series TXH and LXH
models only.)
10 and 10D: Lubrication should not be required
for the first 2–3 months of continuous use. Then,
approximately every two weeks of use, lubrica-
tion of the front and back ends of the handpiece
is required. Follow the detailed instructions that
come with your handpiece.
8D, 10D, 15D, 18D and 20D Handpieces with
Duplex Spring Connections: Approximately every
20 hours of operation apply 1 or 2 drops of Fore-
dom oil (Part No. MS10005) into the hole in the
duplex spring collar next to the sheath connector.
This will provide sufficient lubrication for both
the duplex spring connection and the handpiece
spindle.
15 and 15D: Clean off any dirt to prevent foreign
matter from falling inside the handpiece. Put two
drops of Foredom oil into the oil hole in the side of
the housing. Run the handpiece slowly to distrib-
ute the oil. Lubricate every 100 hours of use.
50 and 50C: After every 200 hours of use you
should clean and lubricate this handpiece. The
old grease must be cleaned off of the interior cam
chamber and replaced with new lubricant (Part
No. MS10008). Follow the detailed instructions
that come with your chisel handpiece.

Foredom’s wide assortment of rotary accessories
makes your flexible shaft power tool very versatile.
Use it for grinding, sanding, carving, engraving,
brushing, cutting, buffing, and polishing on virtually
any material. The Foredom Accessory Catalog of-
fers the right accessories for your specific
applications. Accessories may be purchased from
your local dealer or directly from Foredom.
Always let the speed of the power tool
do the work.
Avoid forcing the tool or applying too
much pressure.
Experience will help you choose the right speed for
the work you are doing. It’s always a good idea to
practice on a scrap piece of the same material you
plan to use to determine the best accessories
and speeds.
Always follow the manufacturer’s RPM or speed
recommendations when selecting accessories.
Your motor is supplied with a variable speed
control that allows you to operate it at the most
suitable speed for each job. The motor has a
maximum speed rating of 18,000 RPM.
Always use an accessory which has the same
or a higher speed rating than your tool.
Using an accessory with a lower speed rating
can result in serious injury.
Rotary Accessories and Motor Rotation:
Running the motor in forward and reverse can
help to extend the life of mounted abrasive points,
Typhoon
®
burs, buffs, and brushes.
Use only the forward motor direction for fluted
burs and cutters. Most will cut efficiently only when
turning in this direction.
Abrasive Points, Wheels, and Discs
Use Aluminum Oxide (red color) for fast cutting
on high-tensile, tough materials such as steel and
malleable iron. Also use on glass and porcelain, etc.
Aluminum Oxide (white color) points have an ex-
tremely fine grit for producing a fine, high finish on
high-tensile materials including stainless steel and
glass. Rubber Bonded Abrasive Wheels are used
for removing rust and for polishing with various
grits. For best results, use finer grits for finishing
at high speeds and coarser grits for stock removal
at lower speeds. Abrasive Discs are for grinding,
smoothing, and cleaning glass, high speed steel,
and other tough materials.
Ruby Carvers have ruby crystals firmly bonded to
a metal frame. These long lasting abrasives provide
a smooth finish on hard materials such as steel,
porcelain, glass, acrylic, soft and precious metals
and wood.
General Accessory Recommendations
Scotch-Brite
TM
Radial Bristle Discs from 3M have
thin flexible plastic bristles that get into hard to
reach areas on flat and curved surfaces. Use on
metal, acrylic, plaster, ceramics and wood without
the need for compounds. These long lasting
abrasives come in many size diameters and grits.
Unique CeramCut Blue Stones are made from a
mixture of special man-made ceramic grain and
aluminum oxide bonded together. The ceramic
provides a faster cutting action and is more durable
so burs hold their shape longer than standard abra-
sives. They are ideal for use on any hard metal such
as steel, stainless steel, chrome cobalt, platinum
and titanium, as well as on wood. Unique V Stones
have extra hard and long lasting vitrified aluminum
oxide and ceramic grain with a special glass bead
binder that makes them extremely long lasting,
cool running and very aggressive — 40 to 60 grit.
They work on the same materials as CeramCut Blue
Stones, but much more aggressively.
Unique CW Ceramic Impregnated Polishing
Wheels are used for smoothing and polishing pre-
cious metals including platinum, gold, and silver.
They also work on titanium, chrome cobalt, and all
hard alloys. Wheels are 7/8″ in diameter and come
in six grits.
Burs and Cutters
Vanadium Steel Cutters are suitable for all materials
except hardened steel and glass. They are used for
cutting grooves and countersinking in soft materials,
carving and hollowing woods, slotting and grooving
woods, plastics, etc. Steel Cutters are good for shap-
ing, grooving, slotting and cutting in wood, plastic and
soft metals. Use Carbide Burs on wood, plastic and
tough alloys. Carbide is generally referred to as the
“hardest man-made metal”.
High Speed Fluted Burs are used for fine detailing
work on metal and other hard materials. Generally use
medium speeds for stock removal and higher speeds
for finishing work and when using smaller points.
Cut-Off Wheels are used to cut off, groove, and trim
metal, wood and ceramics.
Unique Typhoon
®
Carbide Burs provide very fast and
aggressive material removal. Made for use on soft
and hard woods, diestone, and plastics (do not use
Typhoon burs on metal). They have aligned teeth that
leave a smoother finish than other types of non-fluted
tungsten carbide burs.
Duragrit
®
Carbides are coated with tungsten carbide
grit. Edges stay sharp and are thin enough for
cut-off applications.
11
Drills
Cobalt Steel & Diamond Plated Step Drills are
used to drill wood, precious metals, mild steel,
bone, and mother of pearl. Cobalt Steel, Diamond
Plated & Diamond Coated Twist Drills, made of
wire gauge steel, can drill extremely fine holes in
stone, ceramics, tile, glass, and hard metals.
Plated Diamond Points & Discs are used to
remove stock from extremely hard materials such
as tungsten and tantalum carbide cutting tools,
dies and molds, broaches, and for grinding and
pre-polishing synthetic jewels and precious met-
als, fiberglass, reinforced plastics, PVC
and ceramics.
Sanding Drums, Bands, and Discs
These are used for removing rust, smoothing
rough surfaces and for sanding jobs on wood,
plastic and metal. (Avoid using too much pres-
sure which will cause clogging or a build-up on
the work surface.) For best results, use medium
speeds for coarser grits and larger diameters. Use
higher speeds for finishing work or with smaller
sizes. Unique 3M Ceramic Purple Coated Abra-
sive Bands and Discs contain patented Cubitron
TM
ceramic aluminum oxide mineral that sharpens
itself with use. They last 2 to 4 times longer than
traditional aluminum oxide discs and remove
material faster with less heat and loading.
Cotton or Felt Bobs and Buffs
Solid Felt Buffs or Bobs are used in combination
with gritty or smooth compounds for a variety of
buffing and polishing operations on plastic, wood,
and metal. They vary in shape and come in three
hardnesses — medium, hard, and rock hard.
Loosely-stitched Soft Cotton Buffs are used
for delicate work on precious metal and during
polishing operations. Generally use high speeds
for cutting down and buffing. Medium speeds are
used for more delicate, precise work and
for polishing.
Brushes
Miniature Power Brushes are generally used on
metal surfaces and hard-to-reach areas. They
are ideal for deburring, surface finishing, edge
blending, roughening to create a good bonding
surface, and general cleaning. Use high speeds
for cleaning and deburring. Medium speeds are
needed when cleaning hard-to-reach areas and
edge blending.
General Accessory Recommendations continued
Compounds
Foredom has seven different compounds. In
addition to Emery, Tripoli, and Red and White
Rouges, there is unique Platinum Blue for pre-
polishing and cutting down platinum and other
metals, and for final polishing unique Platinum
White (8000 grit) that produces a deep luster on
platinum, other metals, and acrylics. Carnauba
is the hardest wax available. It produces a high
luster on wood and painted surfaces.
2″ Wheels and Discs for
Angle Grinder Attachment
Foredom continues to expand its offering of
several types of wheels with 3/8″ arbor holes for
grinding, deburring, shaping, and cutting on
various materials. PSA backed abrasive discs,
screens and velcro heads for sanding on wood,
metal, plastic, glass, stone and more, can also be
used with disc mandrels in Foredom handpieces.
These accessories work with Foredom’s Angle
Grinder Attachment for use on the H.30
®
, H.30H,
or H.30SJ Chuck-Style Handpieces. It is excellent
for a broad range of sanding, polishing and
finishing work.

Maintenance Procedures
Always make sure your power
tool is unplugged when conducting
maintenance procedures!
It is very important to routinely clean your
Foredom
®
Power Tool and lubricate the shaft
(NOT the motor), especially in areas that
generate a lot of dust.
Dirt and improper lubrication are the most
common causes of poor operation and
excessive wear.
Always disconnect power tool before
cleaning or servicing.
Note: The motor has permanently
lubricated ball bearings and does not
require additional lubrication.
Routine Cleaning of Motors
Foredom Motors
need air circulation
through the motor
housing to remove
waste heat and
cool the windings.
Inlet and outlet
slots provide the
means for air flow. However, saw dust and con-
ductive debris (like metal filings or gold dust)
can enter in through these slots. If not cleaned
regularly, dust can collect, making a bridge
between parts, causing an electrical short.
In high dust environments, Foredom
recommends cleaning the motor every
40 hours of use.
To remove dirt and dust buildup, motor brushes
should be removed, cleaned and replaced, and
air should be blown through the motor.
Routine Cleaning and
Lubrication of Flexible Inner Shaft
The shaft should be checked, wiped clean, and
relubricated with grease every 40 hours of use.
With every 200 hours of use, the shaft should
be thoroughly cleaned with solvent and
lubricated. Use Foredom flex shaft grease
(p/n MS10006) or high quality white
lubricating grease.
Be sure to watch shaft and sheath
maintenance videos on www.foredom.net
Exposing the Inner Shaft
1. Remove
handpiece
(see page 5).
2. Loosen set
screw on motor
connector.
3. Slide outer
sheath out of
motor connector
and wipe inner
shaft clean.
4. Apply a very
light coating of
lubrication to
shaft starting
at the top and
working down-
ward to about
one inch from
the handpiece
end. Apply
grease with your finger tip or small brush.
Don’t overdo, apply a light film of grease.
Once the machine is running, the shaft itself
will spread the grease. If too much grease is
applied, the excess will work its way into the
handpiece and eventually seep out between the
handpiece and sheath. For this reason, apply a
bit less near the handpiece end of the shaft.
Never operate the motor with the outer
sheath removed from the flexible shaft.
5. Replace and adjust sheath so that shaft
key tip extends 3/4″ (19mm) from sheath.
Retighten the set screw in motor connector.
See page 5, No. 2.
6. Clean outside of sheath by wiping with
a cloth.
7. Hang motor
over a trash
can and run it
for about 10
minutes before
attaching the
handpiece. This provides enough time for the
grease to warm up, spread and drain off. Wipe
off any excess grease at tip end of sheath.
8. Re-attach handpiece. See page 5.

Always make sure your power
tool is unplugged when conducting
maintenance procedures!
Replacement of
Worn Shafts and Sheaths
Shafts and sheaths last longer when they are
not used at sharp angles or loops, since wear
occurs at the points of greatest friction. There
is no way to avoid ultimate wear, and under
normal conditions a flexible shaft machine may
require several replacement shafts and sheaths
during its lifetime.
To expose the inner
shaft follow steps
1, 2, and 3 on the
previous page.
Next, remove the
motor connector
with 1″ open end or
adjustable wrench.
Motor connector has a left hand thread and
must be turned clockwise (right) for removal.
Installation of New Shaft
1. After removing old shaft, loosen set screw
on the new flexible shaft motor coupling and
slide coupling onto motor shaft.
2. Tighten set
screw securely
onto the flat of the
motor shaft.
3. Grease shaft
prior to putting on
the sheath. (See
lubrication instruc-
tions on page 13.)
4. Slide motor
connector back up
over the shaft and
tighten to the left
(counterclockwise).
5. Slide sheath over flexible shaft with plain
fitting directed toward the motor and into the
motor connector. (Each end of the sheath has
a metal fitting. One is plain, the other has a
groove around it to fit the handpiece.)
6. Adjust the shaft (page 5 and top right) and
tighten sheath set screw in motor connector.
Shaft and Sheath Adjustment
Place the entire
unit on a flat sur-
face with shaft and
sheath extended
straight.
Adjust the
exposed tip of the
flexible shaft at
the handpiece end so that it extends 3/4″
(19mm) beyond the sheath.
This is done by moving the sheath in or out of
the motor connector. When the correct adjust-
ment is made, tighten the screw in the motor
connector.
Replacement of Motor Brushes
Motor brushes should be checked for wear
periodically. When new they are approximately
3/4″ (19mm) long. Replace them when they
have worn to 1/4″ (6mm). To remove brushes,
disconnect motor power cord and unscrew the
brush caps. Remove the worn motor brushes,
replace with new motor brushes, and screw
motor brush caps back on. Be sure to replace
both motor brushes even if one of them is less
worn than the other.

Motor Hangers
Motor hangers securely suspend hang-up motors
above the work bench for ready access to
your work. Safety clips at the top prevent
the motor from jumping or twisting off at
start up and during use. Motors that slip
off an open hook can cause
serious injury.
